The issue I was having was while creating automation in the Arrangement View, my mouse would move sporadically making it impossible to plot anything accurately. This was only present after I upgraded from a 1080p display to my now 4K display.

This issue is for Windows 8 through to Windows 10 and generally happens when the Windows Zoom settings are different from 100%

The other issue that could present itself is that Ableton Live's GUI appears blurry or out-of-focus. I didn't have this issue however, but the fix below fixes both issues.

The solution is pretty simple:

Locate the application "C:\ProgramData\Ableton\Live 9 Suite\Program"

Right click on the Ableton Live program and select properties

Click the compatibility tab

Check the box 'Disable display scaling on high DPI settings'

Click apply and OK.

Hope this helps for those wanting to upgrade to higher resolution displays.
